We woke up today to the nice surprise of having 3G coverage which we did not have yesterday!! Very nice surprise but I have a problem. We have 3 iPhones and 3 iPads in the home, all of them automatically switched to 3G today except one iPad. No matter what I do, reboot, shut off, turn off data and turn back on, nothing is helping. Edge is still working fine, it just won't switch to 3G. Any ideas? Thanks?
